What is the maximum baud rate for STM32F439ZI-Nucleo144 when using USART?
I am using 115200 bits/s for now and was wondering if I can increase that. If yes, how much can I go until? I checked the datasheet for this board and nothing was mentioned about the baud rate.
Resolved! How to use DMA on complementary timer channels in TIM1
I have been trying to start PWM on TIM1 with complementary channels and use DMA to start the PWM. The problem that I have is that only one of the channels will start when I run the program. DMA channel 2 is being used by TIM1_CH1 and I can't find any...
trace_printf using OS_USE_TRACE_SEMIHOSTING_DEBUG works fine with Eclipse and STM32F405, but not with STM32F446 and System Workbench
I have two electronic products that use OS_USE_TRACE_SEMIHOSTING_DEBUG: Microcontroller IDE 1. STM32F405 Eclipse 2. STM32F446 System WorkbenchI use ST-LINK/V2 to debug both of them and...
Resolved! Error in STM32F410 Reference Manual (RM0401 Rev 3) : Wrong block base start address of sector 4
Hey,I found an error in the STM32F410 Reference Manual (RM0401 Rev 3). I'm not exactly sure, if this is the right place to highlight errors in the datasheet, but maybe an employee of ST can verify the error and eventually forward it to the person whi...
HAL_Delay stuck when sdram use as data memory
Hi:I have a custom STM32F746NG board with SDRAM IS42S328200D(Address 11 bits 2^11(Row Address)*2^8(Column Address)*32(bit)*4(bank)). My goal is to use sdram as data memory, I followed example in STM32Cube_FW_F7_V1.16.1\Projects\STM32746G-Discovery\Ex...
PWM Timer Slave not getting triggered by Master
Hello, I am trying to set timer 3 as a master to timer 1 without success. Timer3 is outputting the PWM correctly, but timer1 is not getting triggered by Timer3's PWM Signal. What else am I missing?My board is STM32F429 discovery Here are my settings ...
Resolved! GPIO pin current info
When a GPIO pin is connected to power an external device via Magnetic switch, from the STM32 point of view how does it know if the Magnetic switch is ON/OFF? ON -> Device is powered ON similarly OFF.Can STM32 detects change in current on GPIO pins?A...
STM32L4R7 low-power, power cycling, and the backup domain
Hello,I have some questions relating to STM32L4R7ZIT and the different ways to enter/exit low-power modes or to power cycle, in both cases without losing RTC and backup registers.VBAT is always powered. There is an LSE.I need to understand which boot...
